Benefit Summary HTML
In November 2002, the Idaho Transportation Department (ITD) completed an enhancement of their Road-Weather Information System (RWIS). The project had four objectives:
  • To provide more information, and to make the information more accessible, to ITD maintenance personnel in support of winter road maintenance decision making;
  • To allow data from environmental sensing stations deployed in the future by the ITD to be integrated with data from their two current brands of environmental sensing stations (ESS);
  • To incorporate RWIS data into the ITD "Road Report" traveler information Web page; and
  • Expand RWIS data collection coverage by incorporating non-transportation weather station data.

The project created a new page, the Road-Weather Integrated Data System, or "RWIDS," on the Road Report traveler Web site. The Web page consolidated data from several relevant sources: ITD's two different brands of ESS (previously accessible only to ITD maintenance personnel via two separate user interfaces) as well as a number of ESS, within and bordering Idaho, operated by a wide range of organizations. The Web page also incorporated additional types of weather information drawn from sources including: non-transportation weather data from Meso West consortium, ITD closed-circuit television camera views, and National Weather Service satellite and radar images, watches and warnings. A password-protected version of the RWIDS Web page, containing printing and e-mail alert features not available to the public, was made available to ITD maintenance personnel.

The evaluation of the ITD RWIS integration project employed a before-and-after study approach focusing on three major areas: RWIDS as an ITD maintenance information resource, RWIDS as a traveler information resource, and RWIDS as a data integration platform. Before (pre-deployment) data were collected in 2001 and 2002, the system was made operational in November 2002, and ITD maintenance personnel were trained during the first winter season (2002—2003). After (post-deployment) data were collected during the second winter season (2003—2004).

In November 2002, the Idaho Transportation Department (ITD) completed an enhancement of their Road-Weather Information System (RWIS). The project had four objectives: 1) To provide more information, and to make the information more accessible, to ITD maintenance personnel in support of winter road maintenance decision making; 2) To allow data from environmental sensing stations deployed in the future by the ITD to be integrated with data from their two current brands of environmental sensing stations (ESS); 3) To incorporate RWIS data into the ITD "Road Report" traveler information Web page (http://164.165.237.41/apps/roadreport/); and 4) Expand RWIS data collection coverage by incorporating non-transportation weather station data.

The project created a new page, the Road-Weather Integrated Data System (http://itd.idaho.gov/apps/rwids_public/), or "RWIDS," on the Road Report traveler Web site. The Web page consolidated data from several relevant sources: ITD's two different brands of ESS (previously accessible only to ITD maintenance personnel via two separate user interfaces) as well as a number of ESS, within and bordering Idaho, operated by a wide range of organizations. The Web page also incorporated additional types of weather information drawn from sources including: non-transportation weather data from Meso West consortium, ITD closed-circuit television camera views, and National Weather Service satellite and radar images, watches and warnings. A password-protected version of the RWIDS Web page, containing printing and e-mail alert features not available to the public, was made available to ITD maintenance personnel. This lesson is based on a Federal Highway Administration sponsored independent evaluation of the ITD RWIS Integration project.
